Amazon Prime is available at a 20-percent discount if you sign up on Friday

Anyone who uses Amazon even semi-regularly should have or at least considered getting Amazon Prime. The biggest draw for the annual subscription is free two-day shipping on eligible items. In some cases, Prime Members can even get same-day delivery in 29 major cities. The annual cost of a membership is normally $99, but on November 18 from 12:00 a.m. ET to 11:59 p.m. ET you can save $20!

The savings is to celebrate Amazon Prime’s new motoring show The Grand Tour. The show features the trio formerly behind the BBC hit Top Gear, now starring in their own Prime exclusive show. Even if you are not particularly tickled by a show about cars, you can’t go wrong saving on a Prime membership.

In addition to the shipping benefits, Prime members enjoy access to a number of free services exclusive to Amazon, including Prime Video, which includes unlimited streaming of thousands of movies and TV shows. Members can also purchase subscriptions to premium channels like Starz and Showtime. Prime Music allows users to stream unlimited ad-free music including millions of songs and hundreds of pre-selected playlists.

Members have access to the Kindle Lending Library which allows users to borrow one Kindle title per month for free. These titles are only accessible on Kindle e-readers, Fire tablets, or Fire phones. Please note, though, that there is a separate Prime lending library for those who use the Kindle reading apps. In addition, Prime members get early access to Lightning deals on Amazon.com.

If you’ve ever been interested in some or all of these extra bonuses from Amazon, but your wallet argued otherwise, consider saving on November 18. Enjoy a year of Amazon Prime benefits for only $79. The signup link goes live on Amazon’s website at midnight on November 17.
